PACKING DEVICE FOR TUBNABLE IlUNQTEGN TUBES PARTS.

lltl' RECIPROCATING .MACHIN-E Application filed April 9. 1924, Serial No. 705,341 and in fiweden April 6. 1923.

This invention relates to a packing device i noble junction tubes in reciprocating ins-chine parts, for 11 nice in internal co1n J11 engines he pistons cooled by such eng .iies thelcooling fluid is,

co: ducted through a turntable at the one side of the crossthrough the cross-head and channel in the hollow piston rod through a. H to the wiingpiston andishenceconductcd through onotherichennel in the piston rod to the other side of the cross-head; 'f'lioru where i is discharged through ,a junction tube Whi chvis also tunnehle with relation to 155 the cross h 1d. sislcn'own it istin this case of consiu hie importance that the cooling fluid is cnted fronitoicing its one} out so as to be mixed With the oilstorediin the lower pertiot the engine or, inother words, 20 that the circulation system for thecooling tluid is entirely tree fronileahege. Hitherto, this hes caused greet ,difi lculties,portion:

hirly of the tnrnehle junction tubes or" the cross-heed and also at other,turnahlejunc- 25 tion tubes of the fluidconduit, since, due to the unavoidable radial stresses occurring n Len runnin the engine, the'heorings ofthe in on tubes as Well as the peel:-

By sucn means the re red so ely by the he ringsot the h have no connection With Wheres th tree fut!

thus, rediw X? p In the annexed drnwi igone term of embodiment of a packing" device according to this invention are shown used in an internal junction tube is provided with .or iorined r n onhccted to nfi udoconcombustion engine having :1 piston co ole: byfiuid.

Referring to the so cross-heed hnviilg ri 7 piston rod The piston rod 52 is hollow known manner end provided with a cent troll arranged 4 pc 3, Jetween which and the well of the i re is "formed an annular channel 4 lezidii to the interior oil the piston and serving hernlly, as e supply conduit tor the cool. 1 fluid, the pipe 3 forming the discharge conduit for the cooling; fluid from the piston. The junction tube 5 ,turnshlewjth relation to the ore s henil l mounted at 6. Provided in thejunction tube .5 is according to thc'im'ention pipe '7 e:-:- tending through the cross-head, a paclm 0 5 being providedbetween said pipe and the junction tube. At the inner end directed towards the chm'zncl. 1: pipe 7 is pr vided with an annular jllange 9, pressed tightly as net 21 sent 11 in the pi ton red by me; 011:1 sleeve 10 sc -en'- thieedcd at its outer end. The outer diameter of the pipe 1 liBF-Slilitll the inner dien'lcter of the sleeve 10, so that the pipe T will be freely susi pcnded between tho seat 11 and the connection inlthcjunctiontnhe 5. By such nieunsthe pecking Send the connection 12, respectively, will, practically heentrelieved from the 1 :1 is occuri on reciprocating the cross-heed, the said stresses heing received by the heajr- (3.

In the 7 ent other end of the junction tube 5, which in. lillOWD. nuance turnahly mounted at 14: in a swingehle conduit 15 for the cooling fluich is provided with so elastic extension 16 freely suspended to e. i port of iength, a packing being provided between the free end of sols extension and a guile 17 formed in the LGil- 1 designates the in the piston rod the duit 15. It is obvious that the radial stresses which has no communication with the fluid piston rod, as shown.

If desired, the packing at the fluid conduit 15 may, obviously, be constructed in the same manner as is the packing in the crosshead and, further, the conduit 1.5 may be provided with such a packing also at the point 14. Further, it is to be noted that the seat 11 for the pipe 7 may also be formed in the cross-head proper instead of in the Besides, the other end (not shown) of the conduit 15 may be provided with packing device according to the invention.

l i hat I claim as new and desire to secure by Letters Patent of the United States of America is 1. In a machine having reciprocating parts, the provision of fluid junction tubes turnably mounted in said reciprocating parts, said turnably mounted tube being provided with an elastic pipe freely susjJe'nded to a certain part of its length, a iackin bein arovided between said elastic arts said turnabl mounted tube bein rovided with an elastic pipe freely suspended to a certain part of its l ngth, a packing being provided between said elastic pipe and the part surrounding itand turning with relation to said pipe, the bearings of said turnably mounted junction tube being disposed wholly out of communication with the fluid conduit formed by said tube and said elastic pipe.
